C1q antibody

Catalog No. ABIN457964

Product Details anti-C1q Antibody

Target: C1q (Complement Fragment C1q (C1q))

Reactivity: Human

Host: Goat

Clonality: Polyclonal

Conjugate: This C1q antibody is un-conjugated

Application: Immunodiffusion (ID), Immunoelectrophoresis (IEP), Radial Immunodiffusion (RID)

Specificity: The antiserum does not cross-react with any other component of human plasma. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins since they frequently share antigenic determinants. of this antiserum has not been tested in detail.

Characteristics: Precipitating polyclonal goat antiserum to C1q fragment ofC1 component of human complement

Purification: Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies cross-reacting with other with other plasma proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.

Immunogen: C1 component of human complement is a complex of three glycoproteins: C1q, C1r and C1s. C1q has a molecular weight of 492.000 and is present in plasma in an average concentration of 80 µ g/ml. It consists of a complex of 18 polypeptide chains of three different types, A, B and C, 6 of each type. The subcomponent C1q is responsible for the binding of C1q to immuno-complexes an membranes via the Fc portion of the immunoglobulin. The subunit C1q is isolated as a homogenous protein for use in antiserum production. Freund’s complete adjuvant is used in the first step of the immuniza-tion procedure.

Isotype: IgG

Application Details

Application Notes: In precipitating techniques as immunoelectrophoresis and single or double radial immunodiffusion to identify the presence of C1q or C1q containing complexes in human plasma or other body fluids or to determine its concentration. The presence of non precipitating antibodies has not been assayed. This does not exclude the use of the antiserum in more sensitive non-precipitating antibody-binding techniques if proper controls are included.

Restrictions: For Research Use only

Handling

Format: Lyophilized

Concentration: Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal goat serum. No foreign proteins added. Antibody titre: Precipitin titre 1:32 when tested against in agar-block immunodiffusion titration against appropriate con

Buffer: Delipidated, heat inactivated, lyophilized, stable whole antiserum

Preservative: Without preservative

Storage: 4 °C/-20 °C

Storage Comment: The lyophilized conjugate is shipped at ambient temperature and may be stored at +4°C, prolonged storage at or below -20°C. It is reconstituted by adding 1 ml sterile di stilled water, spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -20°C. Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4°C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the immunoconjugate.

Target Details for C1q

Target: C1q (Complement Fragment C1q (C1q))

Alternative Name: C1q Fragment of C1 Component of Complement (C1q Products)

Synonyms: AI255395 antibody, C1q antibody, complement component 1, q subcomponent, alpha polypeptide antibody, C1qa antibody

Background: The reactivity of the antiserum is restricted to C1q. In immunoelectrophoresis and radial immunodif-fusion (Ouchterlony), using various antiserum concentrations against fresh normal human plasma a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified C1q protein. Complexes containing C1q may also react with the antiserum. No reaction is obtained with C1r, C1s or any other plasma protein component or serum
